After transmigrating into Zhou Qiong, the final sect master of the Netherworld Sect, he opens his eyes to find the seven great righteous sects surrounding the mountain with their armies, while the sect elders plot to usurp his position. The original host has suffered a cultivation deviation and lost all his power. At the moment of life and death, the Myriad Demons Apprenticeship System awakens. Every disciple he takes on rewards him with supreme cultivation and peerless techniques. The stronger his disciples become, the stronger their sect master becomes. Zhou Qiong recruits countless prodigies from across the heavens as his disciples. Before long, demonic sect disciples have spread throughout the Three Realms, numbering over ten trillion. When ten trillion demonic soldiers obey his every command, all immortals and Buddhas bow before him. From that moment on, Zhou Qiong rules the Three Realms and stands invincible throughout the heavens.
